Firstly I want to start off with positive remarks about the drama that I think are praiseworthy:
- Casting: In my opinion, each actor and actress perfectly executed their given roles - especially the main lead. Honestly, I didn't think Song Kang and Kim Yoojung's pair would have such a good chemistry, but seeing their both on and off-camera interactions proved me wrong.
- Visual effects: They made the series more visually pleasing to watch. And I loved the blue-ish hues that was present in most of the scenes.
Now let's talk about the plot of the drama that was the main downside of the whole series.
- The main thing that I hate about this and many other kdramas that's been released in the past few years is the inconsistency of the plot. They start off great. You'll think it's going to be the best drama you've ever watched, but when you reach the middle of it you'll realize that you've been completely mistaken about it.
By the trailer of the series, I've expected it to have arranged marriage as a main trope (and maybe if they sticked to it, the drama might have been much more successful? idk). But the whole hired killer to crime mystery plot ruined everything. The way writer kept traumatising Dohee with all of the 'almost been killed' events - couldn't they think of something else? (I understand that it's just fiction but still)
- The plot with No Sumin being the person behind all of the murder attempts also feels strange. I feel like it would have been better if it was someone like Ju Seokhoon who seemed all innocent but ended up having reasonable intentions to kill both Madam Ju and Do Dohee.
- And I agree that the plot just felt like a recycled version of older legendary kdrama plots (like Goblin, Doom at your service, Strong woman Do Bongsoon and etc).
Overall, I think My Demon is a good kdrama option to watch when you feel stressed and just want something to entertain yourself
